英文:
During the step script of gitlab Could not find or load main class sh after load docker image
问题
Executing "step_script" 阶段的作业脚本 00:01 使用 Docker 镜像 sha256:75eb8c27787ee5c64311d798c9c0d2991a89024b516908 用于 gitlab-my_repo/maven3-jdk-8-git:V0.1，摘要为 gitlab-my_repo/maven3-jdk-8-git@sha256:febfe8e272bb8ccbb01116e7a177b979b53c080f11cafc ... 错误: 无法找到或加载主类 sh
当我使用 CI_DEBUG_TRACE=true 时，日志中没有其他内容...
对我来说，这是 Java 中的类路径问题，但为什么是 sh 而不是 src/java/class.main...
我们的 GitLab Runner 使用 Docker Dind，并且 maven3-jdk-8-git 的自定义镜像脚本如下：
FROM maven:3.6.0-jdk-8
ENV TZ Europe/Paris
ENV http_proxy XXXXXXXXXXXXXXXXXXX
ENV https_proxy XXXXXXXXXXXXXXXXXXXX
RUN sed -i s/deb.debian.org/archive.debian.org/g /etc/apt/sources.list
RUN sed -i 's|security.debian.org|archive.debian.org/|g' /etc/apt/sources.list
RUN sed -i '/stretch-updates/d' /etc/apt/sources.list
RUN echo "Install Git" && \
apt-get update && apt-get install -y apt-transport-https ca-certificates apt-utils bzip2 git && \
rm -rf /var/lib/apt/lists/* && \
# 修正 Maven 以删除阻止的镜像
line=$(grep -n maven-default-http-blocker /usr/share/maven/conf/settings.xml | awk -F: '{print $1}') && \
echo sed -i -e "$((line - 1)),$((line+5))d" /usr/share/maven/conf/settings.xml
COPY ./settings.xml /tmp/settings.xml
ENTRYPOINT ["/usr/bin/java"]
我在 Dockerfile 中尝试了这行代码：RUN java -classpath /bin/sh sh，但在构建我的 Dockerfile 时出现了相同的错误（无法找到或加载主类 sh）。

Error: Could not find or load main class sh
when i use CI_DEBUG_TRACE= true nothing else in the log..
For me it is a problem of classpath in java but why sh and not src/java/class.main...
Our gitlab runner work with docker Dind and the script of the custom image of maven3-jdk-8-git is :
FROM maven:3.6.0-jdk-8
ENV TZ Europe/Paris
ENV http_proxy XXXXXXXXXXXXXXXXXXX
ENV https_proxy XXXXXXXXXXXXXXXXXXXX
RUN sed -i s/deb.debian.org/archive.debian.org/g /etc/apt/sources.list

RUN sed -i '/stretch-updates/d' /etc/apt/sources.list
RUN echo "Install Git" && \
apt-get update && apt-get install -y apt-transport-https ca-certificates apt-utils bzip2 git && \
rm -rf /var/lib/apt/lists/\* && \
\# Correction du maven pour supprimer le mirror bloquant

COPY ./settings.xml /tmp/settings.xml
ENTRYPOINT \["/usr/bin/java"\]
I try this line in the dockerfile : RUN java -classpath /bin/sh sh
and i have the same error in the build of my dockerfile lol (Could not find or load main class sh)

你的镜像包含 ENTRYPOINT ["/usr/bin/java"]，这是导致问题的原因。GitLab CI 期望用于作业的镜像要么没有定义 ENTRYPOINT，要么具有 shell 入口点。
你可以从镜像中删除 entrypoint，或在你的 .gitlab-ci.yml 配置中覆盖它：
myjob:
image:
name: my/custom/maven-image
entrypoint: [""]
script:
- echo "hello gitlab"
英文:
Your image includes ENTRYPOINT ["/usr/bin/java"], which is causing this problem. GitLab CI expects the images used for jobs to either have no ENTRYPOINT defined, or have a shell entrypoint.
You can either remove the entrypoint from the image or override it in your .gitlab-ci.yml configuration:
myjob:
image:
name: my/custom/maven-image
entrypoint: [""]
script:
- echo "hello gitlab"
